Power BI Log Analytics for Analysis Services Engine - Refresh fails

Hi all.

I'm having the same issues in my tenant as well. It had been running perfectly since the public preview came out. There are a few things going on:

1.  The template app (Power BI Log Analytics for AS Engine (Preview) | Microsoft AppSource) fails to refresh with the error:

   Web.Contents failed to get contents from 'https://api.loganalytics.io/v1/workspaces/a8911362-bb6c-4629-aed1-81570c0f6e1d/query?query=%0A%2F%2F%20Refreshes%20can%20contain%20several%20CommandEnd%20and%20DiscoveryEnd%20events%20that%20share%20the%20same%20rootActivityId.%20This%20report%27s%20data%20model%20typically%20has%20these%20in%20the%20Operation%20table%2C%20however%0A%2F%2F%20to%20keep%20these%20events%20grouped%20together%20we%20move%20such%20events%20to%20the%20Suboperation%20table.%0Aset%20notruncation%3B%0Alet%20workspaceIdList%20%3D%20dynamic%28%5B%2750EA7149-43DC-4DE3-8E56-4D5DBBC83E8F%27%2C%20%27C839BDCB-81B5-4DC3-9F92-818FE71432A1%27%2C%20%2780FA5101-D77B-4AC3-B86A-EEAFE28E64AC%27%5D%29%3B%0A%0Alet%20startDate%20%3D%20startofday%28ago%2813d%29%29-%20720m%20%3B%0Alet%20startIngestionTime%20%3D%20datetime_add%28%27hour%27%2C%2020%2Ctodatetime%28startDate%29%29%3B%0Alet%20endIngestionTime%20%3D%20datetime_add%28%27hour%27%2C%204%2Ctodatetime%28startIngestionTime%29%29%3B%0A%0A%0APowerBIDatasetsWorkspace%0A%7C%20whe' (400): Bad Request. The exception was raised by the IDataReader interface. Please review the error message and provider documentation for further information and corrective action.

2. The template app (microsoft/PowerBI-LogAnalytics-Template-Reports: The repository hosts Power BI template files that can be used to analyze Power BI data after you send it to Azure Log Analytics. (github.com)) also gets this error in the PQ function "fnGetOperationsExceptRefreshes" specifically the in the KQL statement where it seems the fields 'WorkspaceId' and 'WorkspaceName' are no longer in the data... 

   'distinct' operator: Failed to resolve scalar expression named 'WorkspaceId'

3. Logs in the Azure workspace stopped updating on the ~2 weeks ago.
